Molecular Characterisation of Faecal Bacterial Assemblages Among Four Species of Syntopic Odonates.

Factors such as host species, phylogeny, diet, and both timing and location of sampling are thought to influence the composition of gut-associated bacteria in insects. In this study, we compared the faecal-associated bacterial taxa for three Coenagrion and one Enallagma damselfly species. We expected high overlap in representation of bacterial taxa due to the shared ecology and diet of these species.

, a new genus of Ichneumoninae (Hymenoptera, Ichneumonidae) from Peruvian Amazonia.

A new monotypic genus of ichneumonine parasitoid wasps (Hymenoptera, Ichneumonidae, Ichneumoninae) is described from Peru; is described to accommodate The new genus is morphologically very distinctive and can be easily separated from all known ichneumonine genera. By describing from the lowland rain forests of Peru, we aim to draw attention to the considerable diversity and morphological variation of the Amazonian ichneumonine fauna.

Cryptic biodiversity of tropical hesperiid caterpillar-attacking parasitoid wasps: three new species of Townes (Hymenoptera, Ichneumonidae, Cremastinae) from Costa Rica and Perú.

Background: We describe three new species of the previously monotypic genus Townes from Central and South America: and from Costa Rica and from Peru, all of which emphasise the unknown parasitoid insect diversity yet to be revealed in the tropics.

New Information: Host relationships of the two Costa Rican species are described in detail. In addition, it is inferred that the wasps find and oviposit in the caterpillar when it is exposed at night, rather than when it is concealed during daylight hours.

Steel Manufacturing EAF Dust as a Potential Adsorbent for Hydrogen Sulfide Removal.

Electric arc furnace dust (EAFD) is a high-volume steel manufacturing byproduct with currently limited value-added applications. EAFD contains metal oxides that can react with HS to form stable sulfides. Hence, the valorization potential of EAFD as an adsorbent material for syngas HS removal was investigated.

Metabarcoding prey DNA from fecal samples of adult dragonflies shows no predicted sex differences, and substantial inter-individual variation, in diets.

Sexes often differ in foraging and diet, which is associated with sex differences in size, trophic morphology, use of habitats, and/or life history tactics. Herein, strikingly similar diets were found for adult sexes of a dragonfly (), based on comparing 141 dietary taxa identified from the metabarcoding of mitochondrial DNA archived in feces. Arthropods in > 5% of samples included five species of dipterans, two hemipterans, two spider species and one parasitic mite.
